Nova

• If nova is not installed, install with:

``` bash

npm install @mynthai/nova

```

Or run without installing via npx (replace all nova usage with

npx @mynthai/nova)

Deterministic Parsing (MUST)

• Use structured output: -j/--json or -t/--toon (never parse human

output).

• Always evaluate BOTH:

• Process exit code (0 success, 1 error)
• Structured status (ok or error)

• On error: read error.message and error.exitCode (if present).

Safety / Financial Safeguards (MUST)

• Before any financial action (send, withdraw):

• Confirm current network via nova config get network.
• Confirm intended network with user (mainnet vs testnet).
• Confirm amount and destination/address (and blockchain for

withdraw).

• send is non-idempotent:

• Never retry nova send blindly.
• If outcome is uncertain, verify via nova -t balance (safe).

• Treat claimUrl as a secret credential:

• Never paste into shared chats/tickets/docs or persistent logs.

• Key material is secret:

• Never log/export keys or phrases into shared/persistent contexts.
• Warn user before export operations.

Wallet Types

• Email wallet: created via nova login (email + verification code).

• Private-key wallet (default if not logged in): auto-created; user must

back up:

• nova export key
• nova export phrase

Networks

• nova operates on mainnet or testnet.
• Fresh install default: testnet.
• Network setting persists; funds/addresses/balances are isolated per

network.

Commands:

nova config get network
nova config set network <mainnet|testnet>

Exit Codes

• 0 = success (still parse status).
• 1 = error (inspect error.message).

Output Modes (for agents)

• JSON: -j, --json
• TOON: -t, --toon

Commands (syntax preserved)

Auth

Request login code:

nova login request <email>

Confirm code:

nova login confirm <code>

Options:

• -j, --json
• -t, --toon
• -f, --force (request only): overwrites existing private-key

wallet; warn user.

Account

Address:

nova address [blockchain]

• Default blockchain: mynth

• Supported blockchains:

• base
• cardano
• hyperliquid
• mynth
• plasma
• solana
• stable
• sui
• tron

Balance:

nova balance

Notes:

• balance is USD-denominated.
• currency is always USD.

Send (FINAL ACTION)

nova send <amount> [destination]

Options:

• -d, --dry-run — Validate and preview without submitting

Behavior:

• If destination omitted:

• Creates claim link (claimUrl)
• Funds leave wallet immediately.

• If destination provided:

• Sends directly.

• destination may be:

• An email address (creates or targets an email wallet).
• A nova wallet address.
• A supported external blockchain wallet address

(network-dependent).

Rules:

• No interactive confirmation.
• Non-idempotent: re-running sends again.
• Use --dry-run (-d) to validate inputs and preview without

submitting.

• Always confirm with user whether destination is an email address or

wallet address before execution.

Post-check:

• Parse status and confirm result.sent: true.
• Surface result.txId when present.
• If claimUrl present, treat as secret.

Success example (TOON):

status: ok
result:
  sent: true
  amount: "1"
  txId: d32c966fd4302673455eb790b66e3efc331ef7aace412c73b8917ba0bb37ace8
  claimUrl: "https://preview.mynth.ai/c/mto3M1JEa6Hr0UFRCBGjOg"

Claim Links

Properties (when nova send has no destination):

• One-time use.
• Do not expire.
• Revocation: creator must claim it themselves (redeem back to own

wallet).

Withdraw (FINAL ACTION)

nova withdraw <amount> <stablecoin> <address> <blockchain>

Options:

• -d, --dry-run — Validate and preview without submitting

Rules:

• Confirm:

• Sufficient balance
• Network
• Stablecoin support
• Address + blockchain compatibility

• Parse status.

• Surface result.txId when present.

Verification (safe):

nova -t balance

Stablecoin Support

amount.

gets full amount.

• External withdrawals:

• May incur chain fees.
• Fees are calculated at execution.
• Fees are deducted from withdrawal amount (not separate).

Rate Limits

If rate-limited, structured output indicates an error and includes a

message like: “Rate limited. Try again in N seconds”.

Rules:

• Do not retry immediately; respect the wait time.
• Never retry send blindly after a rate-limit error.
• If unsure whether send executed, verify via nova -t balance.

Error example (TOON, insufficient balance):

status: error
error:
  message: 3tkv5qrm43jtjf86x3ks5l6jpjgpyw7n8424pm must have at least balance of 1000000
  exitCode: 1

Key Management (security-critical)

Export:

nova export phrase

Import:

nova import key
nova import phrase

Rules:

• Warn user: exporting reveals secrets.
• Never store or share exported key/phrase.
